Zero-Knowledge Rollups: Why Layer 2 scaling is the real deal
Instead of verifying every transaction on the main blockchain, ZK-Rollups bundle thousands of transactions off-chain and post a compact cryptographic SNARK/STARK validity proof to Ethereum Layer 1. Gas fees drop by 99% while inheriting 100% of L1 security.

Smart contract security: What 100 audited Solidity repos taught me
Most critical vulnerabilities aren't complex zero-day cryptographic exploits. They are simple reentrancy oversights, unchecked return values from ERC-20 transfers, and improper access controls where `onlyOwner` was accidentally omitted. Fundamentals matter infinitely more than fancy tricks.
